[0021] In this embodiment, it also includes two conductor mounting seats 2. The two conductor mounting seats 2 are respectively arranged at both ends of the reference conductor. The conductor mounting seats 2 are fixedly connected to the tension sensor 3, and the conductor mounting seats 2 are rotated The bearing 8 rotates and cooperates with the reference conductor 1. Through this structure, it is more conducive for the reference conductor to rotate under the action of wind and ice-coating gravity and form a uniform cylindrical ice coating on its surface, and it is convenient to install the reference conductor. The rotating bearing 8 is a deep groove ball bearing. Through this kind of bearing, it can withstand a relatively large load, especially when there is icing on the surface of the reference conductor, and it can ensure the smooth rotation of the reference conductor even under the load. Performance, thereby ensuring the stability of the work of the present invention.

[0022] In this embodiment, the ice melting unit includes an insulated heating wire 7 and a copper tube 6. The insulated heating wire is arranged in the copper tube 6, and the copper tube 6 is arranged inside the reference conductor 1. Through this structure , It can be beneficial to melt the ice on the reference conductor after receiving the ice melting command, to ensure the synchronization of the reference conductor and the transmission line, and the structure is compact, will not affect the surface of the reference conductor, thereby ensuring the accuracy of the monitoring results. The tension sensor and the insulated heating wire are powered by a power transformer or a solar battery, which can ensure the continuous and stable operation of the present invention without manual intervention in the real-time monitoring of icing of the power transmission circuit, especially for remote and complex and harsh environments. It avoids the hidden safety hazards of manual intervention and manual intervention.

[0023] In this embodiment, the suspension bracket is a connecting rod 4, one end of the connecting rod 4 is fixedly connected with the tension sensor 3, and the other end is provided with a hanging ring 5. This structure facilitates the fixed installation of the present invention on the transmission line It is installed under the ice melting device of the power transmission line, and is easy to install. Among them, there are two connecting rods and tension sensors. Both ends of the reference conductor are provided with a tension sensor and a connecting rod, which is conducive to the fixation of the reference conductor. And rotation, but also conducive to the monitoring of icing.

[0024] In this embodiment, the ice coating data monitored by the tension sensor 3 is transmitted to the control unit or monitoring center of the ice melting device of the power transmission line in a wired or wireless manner.

[0025] In this embodiment, the two conductor mounting bases 2 are both provided with mounting holes 10, wherein the mounting hole 10 of one conductor mounting base 2 is a blind hole, and the mounting hole 10 of the other mounting base 2 is a through hole. The two ends of the tube 6 are respectively fixedly arranged in the mounting hole 10 and the insulating heating wire 7 passes through the mounting hole 10, which is a through hole. This structure facilitates effective fixing of customs clearance on the one hand, and insulates the electric heating on the other hand. The wire is electrically connected to an external power source to ensure that the reference conductor can be smoothly melted when ice is required to melt. More importantly, it can be ensured that the reference conductor can rotate smoothly, thereby ensuring the stability and accuracy of the present invention.
